Optical fiber multiplexer
MPM-2000 Ocean Optics

The MPM-2000 Fiber Optic Multiplexer takes light to a spectrometer or from a light source connected to one of the input ports and distributes it to either 8 or 16 outputs. The light is distributed through the output ports in sequential order, with switching times between channels of less than 150 milliseconds. Multiplexers often are found in process industries, where multiple locations need to be measured with one spectrometer channel and/or light source.

Ocean Optics offers four different multiplexer versions.
High-precision Instrument

All versions of the MPM-2000 include a DC motor, which has excellent speed control without sacrificing power. The motor is on a rotator block and includes an encoder, which converts the incremental movements into a digital pulsed output. Each channel in the multiplexer has a collimating lens connecting to an internal optical fiber system. The MPM-2000 provides accurate measurements with a repeatability of 99% and offers optical throughput of approximately 50%.
